<h2>RNA Polymerase</h2>

Explanation:

  • RNA polymerase, a chemical in the cell, is  answerable for making mRNA from the  right quality. RNA polymerase is like  DNA polymerase, yet it makes a RNA strand  as opposed to a DNA strand. The promoter region of DNA Helix is attached by  RNA polymerase.
  • It pulls in nucleotides that supplement those  on the DNA strand containing the gene of interest. RNA polymerase duplicates one strand of  DNA to make a stretching bit of singlestranded  mRNA. RNA polymerase makes the  mRNA strand in what is known as the 5' to 3'  course.

Chromosomal nondisjunction is the consequence when the homologous chromosomes are not completely separated from each other during meiosis.

While chromosomal translocation is the crossing over of genetic material between two chromosomes.

Only chromosomal disjunction can be seen from the karyotype.

Answer:

e. Mitochondrial

Explanation:

  • This is a case of mitochondrial heredity so correct answer is e. Mitochondrial
  • In this case, the mother transfers her mitochondria to her children. So the child is affected. The male does not pass this trait on to his children.
  • We can see from the lineage that the mother has defective mitochondria so all their children will have defective mitochondria. One of his sons has mitochondrial, but is unable to pass it on to the next generation.
